After entering the vehicle during a remote start, insertand turn the key to ON/RUN to drive the vehicle.
If the vehicle is left running it will automatically shut offafter 10 minutes unless a time extension has been done.
To manually shut off a remote start:
•Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lampsturn off.
•Turn on the hazard warning flashers.
•Turn the ignition switch on and then off.
The remote vehicle start feature provides two separatestarts, each with 10 minutes of engine running, or itprovides one start with 10 minutes of engine running thatmay be extended 10 more minutes. If you press andrelease the transmitter lock button and then press andhold the remote start button on the RKE transmitteragain before the first 10 minutes of engine running timehas expired, 10 minutes are added to the remainingminutes. For example, if the lock button and thenthe remote start buttons are pressed again afterfive minutes of the engine run time, 10 minutes areadded and you now have 15 minutes of engine running.The added ten minutes are considered a secondremote vehicle start.
Once two remote starts or a single start with a timeextension have been used, the vehicle must be startedwith the ignition key before you can use the remotestart feature again.
The remote vehicle start feature will not operate if thekey is in the ignition, the hood is not closed, or if there isan emission control system malfunction.
The engine will turn off during a remote vehicle start ifthe coolant temperature gets too high, or the oil pressureis too low.
Your vehicle was shipped from the factory with theremote vehicle start system enabled. The system maybe disabled through the Driver Information Center (DIC).See “REMOTE START” underDIC VehicleCustomization on page 4-80for additional information.
SeeEngine Exhaust on page 3-34for important safetyinformation when using remote start in a closed garage.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have ormight begin programs to inspect the emission controlequipment on the vehicle. Failure to pass this inspectioncould prevent getting a vehicle registration.
Here are some things to know to help the vehicle passan inspection:
•The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if thekey is in ON/RUN and the light is not on.
•The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determinesthat critical emission control systems have not beencompletely diagnosed by the system. The vehiclewould be considered not ready for inspection.This can happen if the battery has recently beenreplaced or if the battery has run down. Thediagnostic system is designed to evaluate criticalemission control systems during normal driving.This can take several days of routine driving. If thishas been done and the vehicle still does notpass the inspection for lack of OBD II systemreadiness, your dealer/retailer can preparethe vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance candamage the engine. The repairs would not becovered by the vehicle warranty. Always follow themaintenance schedule in this manual for changingengine oil.
This light comes on briefly while starting the engine.If it does not, have the vehicle serviced by yourdealer/retailer. If the system is working normally theindicator light then goes off.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at eachfuel fill. In order to get an accurate reading, the oil mustbe warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. SeeEngine Compartment Overview on page 6-12forthe location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutesto drain back into the oil pan. If this is not done, theoil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towelor cloth, then push it back in all the way. Remove itagain, keeping the tip down, and check the level.

Notice:Using abrasive cleaners when cleaningglass surfaces on the vehicle, could scratchthe glass and/or cause damage to the rear windowdefogger. When cleaning the glass on the vehicle,use only a soft cloth and glass cleaner.
Many cleaners contain solvents that may becomeconcentrated in the vehicle’s breathing space. Beforeusing cleaners, read and adhere to all safety instructionson the label. While cleaning the vehicle’s interior,maintain adequate ventilation by opening the vehicle’sdoors and windows.
Dust may be removed from small buttons and knobsusing a small brush with soft bristles.
Products that remove odors from the vehicle’supholstery and clean the vehicle’s glass can be obtainedfrom your dealer/retailer.
Do not clean the vehicle using:
•A knife or any other sharp object to remove a soil
from any interior surface.
•A stiff brush. It can cause damage to the vehicle’s
interior surfaces.
•Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damagethe interior and does not improve the effectivenessof soil removal.
•Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks andattracts dirt. For liquid cleaners, about 20 drops pergallon (3.78 L) of water is a good guide. Useonly mild, neutral-pH soaps.
•Too much cleaner that saturates the upholstery.
•Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachmentfrequently to remove dust and loose dirt. A canistervacuum with a beater bar in the nozzle may onlybe used on floor carpet and carpeted floor mats. Forany soil, always try to remove it first with plain water orclub soda. Before cleaning, gently remove as muchof the soil as possible using one of the followingtechniques:
•For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into thepaper towel until no more can be removed.
•For solid dry soils: remove as much as possible
and then vacuum.
